Get exchange calendar events in javascript webapp?

Question

I find the documentation provided by microsoft confusing( Link ).

How can I for example get an authentication token and where can I download the javascript libraries? I couldn't find any information on this.

Basically I want to know how to get the calendar of an user in my javascript webapp.

I did try sending an request to

"https://outlook.office365.com/api/v1.0/me/calendarview?startDateTime="+begin+"&endDateTime="+end"

This shows me an authentication popup but after submitting the correct username/mail and password, it doesn't do anything. There is no response back.

To get an access token, you need to use the OAuth2 Authorization Code Grant flow. https://dev.outlook.com/RestGettingStarted walks through the process. Basically you need to register your app to get a client ID and secret, then use those to go through the process.
